17 Save/Recall (Setups, Screens, Data)
• Whether acquisitions are running. When stopped, data comes from the
raw acquisition record. When running, data comes from the smaller
measurement record.
• Whether the oscilloscope was stopped using [Stop] or [Single]. Running
acquisitions split memory to provide fast waveform update rates. Single
acquisitions use full memory.
• Whether only one channel of a pair is turned on. (Channels 1 and 2 are
one pair, channels 3 and 4 are the other.) Acquisition memory is
divided among the channels in a pair.
• Whether reference waveforms are on. Displayed reference waveforms
consume acquisition memory.
• Whether digital channels are on. Displayed digital channels consume
acquisition memory.
• Whether segmented memory is on. Acquisition memory is divided by
the number of segments.
• The horizontal time/div (sweep speed) setting. At faster settings, fewer
data points appear on the display.
• When saving to a CSV format file, the maximum number of data points
is 64K.
When necessary, the Length control performs a "1 of n" decimation of the
data . For example: if the Length is set to 1000, and you are displaying a
record that is 5000 data points in length, four of each five data points will
be decimated, creating an output file 1000 data points in length.
When saving waveform data, the save times depend on the chosen format:
